            Socket soc = svrsoc.accept();
            InputStream is = soc.getInputStream();
            InputStreamReader isr = new InputStreamReader(is);
            BufferedReader br = new BufferedReader(isr);
            String str = br.readLine();

            InputStreamReader isr = new InputStreamReader(System.in);
            BufferedReader br = new BufferedReader(isr);
            String str = br.readLine();
            OutputStream os = soc.getOutputStream();
            PrintWriter pw = new PrintWriter(os,true);
